I take it you are using your laptop to watch DVD etc on your HD TV. I had the same problem where the sound was coming out my laptop. I solved this by going in to the sound options on my computer (which you can access in your control panel) then set your sound default as HDMI. This should solve the problem, just remember to set the default back to the laptops speakers when you are finished using it on your TV. I hope that helps.

I connected my HP8510p via HDMI to my LCD TV and got after a few trials both: Picture and sound!
That's how i've done it:
-Go to the control panel
-Sounds
-Rightclick on the so called "Digital Output Device (HMDI)" and set it as default(same as Realtek HD Audio)

now the sound comes perfectly out of TV speakers!

/edit: Of course you probably also have go to your TV's options and set as sound input the HDMI port.

i was searching for the same thing and saw ur post...... this might help..

The reason it doesn't work is because you have Windows XP. It does not have the required support for HDMI. How ever there may be software from the maker of your audio card's website. You can try there, but most companies have moved away from support of XP when it comes to audio drivers.
Plain and simple a system that has an HDMI port on it and Windows XP is a travesty. Windows XP was not made with these ports in mind.

Yes,hello I need help with the "audio" problem with the connection between my 32" tv and my dell inspiron desktop.the problem is that when I go to sound on the control panel,it shows the hdmi thingy but I cant set it as default! ANY suggestions will be helpful thanks!

Have you read a bit further ?
I experienced the "non selectable as default" problem too, managed to switch back to an older windows HDMI driver which allows it, following advice from this post by rkd993 :
http://ccm.net/forum/affich-79711-laptop-sound-on-tv-with-hdmi-cable#27But I must say it didn't solve the "no sound through" problem, it simply allows to select HDMI as default in my case. :(

Hope it helps you go further than me, and then you could come back and explain how you did. :)

I seem to be having the same issue that you were with the HDMI cables connecting to your TV. I can't seem to figure it out... no matter what I try. I've also noticed that most forums and "help guides" have tips for Vista users only and for myself, I have XP. If you could share your knowledge about this problem you will surely save me a heck of a lot of time and stress.

Hi bunny, if you have vista like I do you go to control panle open sound, now you should speakers and Digital output device (HDMI) and realtek digital output. if you only see speakers that because the other are not shown to make them visable right click below the speaker a box should show up that says show disabled devices ckick on that and it should reviel the (HDMI) then right click on the (HDMI) and set as default! this should fix ya! hope this helps

Please be the one who just might have an idea of how to get sound out of your tv. Yes I did have sound from my (42" LG TV) the first time I conected it to my computer (Vista 64bit), which was good and also a good picture it seemed any flim I put on played OK. But now since I've had to format my computer(some other problem) I still get a good picture but only get back ground sound but no lead talking (well you can hear some thing but its muffled)
I've tied loads of drivers and all that seams to do is mess the computer up, so I dont fancy going down that root again. The HMDI thingie my computer did not reconise it, so I didn't get very far with that I've also tied Vista Audio Changer, That got a dig in the ribs and all. On the display settings it find my tv but when pluging in to my sound card, nothing comes up on the moniter like when you've just pluged in to a TV.

wicked u guys have helpedme solve a problem. Picture was easy I just plugged in the Hdmi cable to my Dell xpsm1530 (awesome laptop) to my new panasonic 50" plasma no sound rather than gettingfrustrated with it I jumpedon here read several posts and got sound! thanks to all for advice!

Hi, I have exactly the same setup as you. Brand new Dell XPS 1530 and new Samsung LCD HDTV. How did you do it as I have connected by HDMI with a good picture but no sound ???? I have configured the sound settings to HDMI and still this doesnt work. Any ideas????
Thanks

Hi mike! To hear sound you will need to purchase an male to male audio cable. I think that will solve all of our problems. You can purchase that at Best Buy or Radio Shack. I'm not 100% sure but I'm going to go purchase it to see if it works. I mean that's the only solution I have came up with since I tried everything else. Now when you get the cable, plug it in the back of the LCD TV where it says PC/HDMI1 (Audio) and then hook it up to the laptop in the headphone jack. IT SHOULD WORK =).

Hi I tried everything you said and I'm still having issues. You said go to "Sound Options" in the "Control Panel" and switch the sound to HDMI but I don't see an option for switching the sound to HDMI. Please help.

Good morning. I have a HP Dell and there appears to only be a "S" port. I purchased the cable and connected the laptop to my Digital TV. However, the laptop icons increase in size as soon as I connect then the screen goes black. Any ideas of what I'm doing wrong? Many thanks!

i have been searching forever to find this. But no one has answered how to do it on a macbook. Can someone please send me a message if you know or think you might know how to Email Id removed for security Thank you so much to whoever answers

That is so funny!!! For about a year I have just been using the HDMI for video and using a cheap set of compact speakers plugged into my headphones jack to play the audio. Tonight as I was setting up my new BRay player I realized that it had audio and video by just using the one HDMI cord and was wondering if this would work on my computer as well. To think this whole time it was such a simple fix. HA! thanks for the info.

if that doesnt work, if nothing works it has to be one thing
there is a hardware conflict/sharing, u need to check it out in your computer system information and you will probably have a 1rq22 hardware conflict

If the sound does not work proberly right click on HDMI and select "Properties" That should open up the properties:) Then go to the 3rd tab and make sure the sound icon doesnt have a little "block" sign!

Enable it. In my case I have 2 high definition audio controller. Disabling one of it will disable the pc speaker & digital audio/spdif. Disabling the other will disable the ATI HDMI output with the tv icon. Enabling both will enable all sound playback device. You can actually open the sound playback device window and see the icon comes and goes as you play around enabling and disabling the audio controller.

Connect the HDMI cable to the Laptop and the TV. Make sure the TV was OFF then Power it on so that the TV will then SEE the HDMI connection.

On the Laptop go to Start > Control Panel > Sounds > Right click on the "Digital Output Device" and set it as default. Depending on your Laptop will make the difference as to the name the HDMI device is under.

THIS IS the catch 22... some Laptop require you restart them after you save the changes, lol....

So while the HDMI cable is STILL plugged in and connected to the TV >>> restart <<< your PC.

Oh and something funny about Microsoft, sometimes you have to play sound in Windows Media CENTER before it will play sound through Windows Media Player.

If that fails... CALL YOUR LAPTOP MAKER, They have Tech Support for a reason

I have been chasing this same problem for several days. None of the recommended solutions have worked to enable the HDMI cable between my Sony Media PC and the Philips TV. So, be sure the HDMI cable is connected and that the HDMI input on the TV is showing the correct type of input ("PC" on my Philips) and of course that your PC is on ;-)

In Windows 7 this is what worked:

Select the Playback devices
(My HDMI device was listed as "not connected")
Select the HDMI device and right click "Properties"
On the next screen for the device click the Properties button
On the next screen for the driver click the "Change Settings" button
Select the Driver Tab, Then go to the "Update Driver" button and select "Browse my computer"
You should see a "High Definition Audio Driver" listed; mine was listed but the driver installed was the standard IDT driver. Install the High Definition driver and then test the system; it should now be working. If you leave the screen open while you test it you can still "Roll back" the driver
Assuming your system is now working, close the various screens and sit back and enjoy your HDMI vision and *sound* :D

All my systems are Windows 7; I suspect you will find a similar option on a Vista machine.

Just wanted to say, this at last allowed me to select HDMI Output as "default" in the sound menu of the "Control Panel" under Vista on my Toshiba laptop (wouldn't let me do that while the "Realtek HDMI" driver was enabled... and this is indicated everywhere as the first step to solution.
Sound still not playing via HDMI cable on my Pioneer amplifier but this has been the frst progress I managed in 2 days, thanksomuch !

Yes!
Thank you very much!
i have windows 7, I just update my driver, and Your driver is up to date. after this I go back and got ATI HDMI Output like default device.
If I have to go back to laptop speakers I just switch default.
Easy!

HDMI is a technology before its time during its time. It's had several modifications, including 1.0, 1.1, 2.1, 3.1 and so forth. While the video quality has always been 1080p, the audio has undergone several changes during the years.

It's possible that the HDMI port on your laptop isn't designed for audio at all. I would recommend looking for an optical, or try jacking your stereo up to the line out. Even if you were somehow successful getting the audio into your tv, HDTV audio is poor at best.

Extend a splitter cable from your headjack to the stereo with the red/white cables. it'll do you well, and most receivers can pro logic ii the audio to make it come through 5.1 quality (or comparable)

I think this is the problem I have. But my laptop is brand new, literally bought last week, surely it should support HDMI audio?
When I go in to my sound settings on Windows 7 it says that the ATI HDMI Output is not plugged in and so I don't have the option to set it as a default device. So it seems like it should work but it is not recognising the cable?
I dunno.. If you could help that would be great.

I just opened my volume control, then clicked on mixer. then on the left part of the mixer there was a scroll down box and I just kept changing the device until the sound came out of my tv.
I have a Dell inspiron laptop btw.

I solved my problem after 3 hours of screwing around. This arose after upgrading from Vista to 7.

Problem - hdmi wasn't showing up under devices for audio output. I reinstalled every driver individually that had to do with audio or video. Nothing worked.

Solution - I eventually downloaded the entire new chipset direct from intel and reinstalled the chipset and all hdmi/graphics drivers from that download. After restart it worked fine. Also needed to download newest itunes, but that worked too.

If you have sounds already playing on the laptop, then you must switch your default to the HDMI then go and re open the program ie itunes. Any other program playing sounds on ur laptop speakers will continue to play through the lap top speakers...

On VISTA do this
Right click your screen
go to personalize
on the left there is an option "connect to a projectror or external display"
Click the speaker picture, and set the default to HDMI by right clicking it and selecting make default.
Close your media programs, and then re-open them and hit play..

Presto! Sound will work!
This wasnt listed in my manual either I had to figure it out.
HOPE this helps, any questions email me.

Im using vista, and hdmi lead.. and iv got picture on my hd tv but no sound. Iv tried to do what youve said and iv set "Nvidia HDMI output" to default and the green bars going up n down but still not coming through tv. Its stopped coming through laptop but not coming through tv. Well gutted! Cant work it out! Any help?

My laptop sets the sound to HDMI automatically when I connect the cable. But then during playback, sound sometimes suddenly (and it seems with no reason) stops coming out of my TV. First time it tried what is described above and it worked (after also closing and reopening Windows Media Player). But now it doens't anymore. I get stuck with the same problem as kyle_d: I set HDMI to default, test it, see green bars going up and down, but hear no sound. I always have to stop playback, reboot my laptop and then it works. For a while... Until it stops again a few minutes later. Maybe an hour or two...
Any hints?

Thankyou so much, this worked straight away. I had been trying all day with the HDMI cable and a guy at the store told me it would never work without an extra audio cable,which I bought.....but even that didn't work. Now I only need the one hdmi cable, thanks again

I finally can figure it out how to get the sound to my LCD TV. All you have to do is changing your laptop screen resolution. Change it to the higest. First, it was @ 1280 x 720. When I changed to 1280 x 800, bummmp...sound went through. Good luck all.

I solved this by opening PowerDVD and from the menu going to :
Settings->audio settings->speaker environment. It was set on "2 speaker". I selected "HDMI" from the pull down list. Sound now came only from the TV. I'm paranoid so I don't turn the computer or the TV on until the HDMI cable is plugged in. Remember to put the setting back to "2 speaker" before you unplug the HDMI cable after watching. I couldn't open PowerDVD afterwards when I forgot this step.

HDMI is not the problem, right click on your mouse or pad, go on volume (it's between your time and volume) you have 3 option playback, recording and sounds. You need to go on Playback den disable speakers, enable HDMI output then enjoy :)
make sure you reverse the way things were (disable HDMI OUTPU AND ENABLE SPEAKERS) otherwise further problem in the future please try not to leave the way things are like for example remove the hdmi cable out of laptop.

After trying it many times with different laptops and different browsers and different LCD, I have figured out that at times you need to restart the browser before LCD would play sound from the browser after connecting with HDMI. I prefer to use Mozilla firefox as it has adblocks addon. And even when you take out HDMI, then again you need to restart your browser to resume the sound.
Hope it helps

Try manipulating the video player such DivX. You should be able to find a sound setting option (could be in preferences, options, tools, etc.) From here you can check the sound option on or off. Try a couple of times if it doesn't work the first time.

yeah my desktop I just got has an hdmi port as well but when I was trying to get sound it would only come from my computer speakers. I eventually figured it out. I made my tv an extension of my monitor thru the graphics controls after I got the tv up I just had to restart my computer with the setting with tv still on and then it finally gave me a sound option for the tv under the sound control panel. set that to default and then u can go back and forth between sounds but u can not get to seperate audios like one for tv one for computer.
